From ad8ee9e77c879bc063bb4f411050c14fd5f6c244 Mon Sep 17 00:00:00 2001 From: Israel Herraiz Date: Fri, 22 May 2026 15:16:26 +0000 Subject: [PATCH 1/8] SolaceIO - fix for data loss during scaling/rebalancing (#36991) Introduced a sequential pending checkpoints tracking mechanism using a TreeMap in the reader. Created a JVM-global ActiveReadersRegistry using weak references to resolve serialized checkpoint marks back to their originating active reader. This enables reliable sequential acknowledgments of checkpoints, ensuring we only ack committed data, while allowing subsequent finalizations to catch up and prevent message leaks (stuckness) if intermediate finalizations are lost. Also synchronized received messages access for thread safety with minimal lock duration (network I/O done outside locks). Fixed initialization order by registering the reader post-construction. --- .../io/solace/read/ActiveReadersRegistry.java | 48 +++++++++++++ .../io/solace/read/SolaceCheckpointMark.java | 52 +++++++------- .../io/solace/read/UnboundedSolaceReader.java | 59 ++++++++++------ .../io/solace/read/UnboundedSolaceSource.java | 4 +- .../beam/sdk/io/solace/SolaceIOReadTest.java | 68 +++++++++++++++++-- 5 files changed, 179 insertions(+), 52 deletions(-) create mode 100644 sdks/java/io/solace/src/main/java/org/apache/beam/sdk/io/solace/read/ActiveReadersRegistry.java diff --git a/sdks/java/io/solace/src/main/java/org/apache/beam/sdk/io/solace/read/ActiveReadersRegistry.java b/sdks/java/io/solace/src/main/java/org/apache/beam/sdk/io/solace/read/ActiveReadersRegistry.java new file mode 100644 index 000000000000..450e5c361cac --- /dev/null +++ b/sdks/java/io/solace/src/main/java/org/apache/beam/sdk/io/solace/read/ActiveReadersRegistry.java @@ -0,0 +1,48 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

Defaults to 30 seconds. - Timeout Detection: UnboundedSolaceReader checks for expired checkpoints during advance(). If a checkpoint is not finalized within the deadline, it is removed from memory to prevent leaks. - Asynchronous Nack: Expired checkpoints explicitly Nack their messages back to the Solace broker using JCSMP settle(Outcome.FAILED) asynchronously via the ackExecutor. - Unit Test: Adds UnboundedSolaceReaderTest to verify the timeout and async nack logic using a mock clock. - Integration Test: Adds test04ReadWithNackAndTimeout in SolaceIOIT using Testcontainers to verify end-to-end redelivery and successful reprocessing with a real Solace broker.
